A brick of ramen noodles having two servings seems absurd if you think of a serving as a single portion that you eat while saving the rest for later, but there was a time when the official government-approved diet prescribed a particular number of “servings” from each food group. I don’t think eating 6-11 servings of bread/pasta/rice/cereal meant that you were supposed to have 6-11 different items, just that “servings” were some kind of standard-ish way of thinking about food, so if you had one portion of noodles that accounted for two servings, that would just let you know that you needed 4-9 more servings that day (if you were someone who fastidiously looked at such information, which most people didn’t and don’t). Now the Food Pyramid is long gone but we still have “servings” on food packages.
Except that “servings” are NOT based on what is proscribed as serving size but based on survey data of what people generally actually do eat as a serving of that sort of food (not necessarily the specific food packaged as it is).
Apparently the typical serving of a bowl of noodle soup is about 8 ounces; not the 16 ounces that a package of ramen makes. Likely that serving of noodle soup is not soup as the main course of a meal.
Packaging of course impacts the however much one feels like eating. And packaged instant ramen may be more of a whole meal. (My memories go back 45 years ago and doctoring it up with leftover veggies, maybe some leftover chicken and/or an egg mixed in as a quick budget friendly dinner.)
